SPECIFICATION forming part of Letters Patent No. 560,746, dated May 26,1896.

Application filed January 1'7, 1896. Serial No. 575,878- (No model.) i

To all whom it may concern;

Be it known that I, CHARLES E. N UTTING, of Hopedale, county of\Vorcester, and State of Massachusetts, have invented an Improvement inSelf-Threading Loom-Shuttles, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters and numerals on the drawings representing like parts. y

This invention relates to loom-shuttles, and

has for its objectthe production of selfthreading devices thereforwhereby the shuttle is automatically threaded as it is thrown throughthe shed fIOlllOllC to the other side. In the shuttle to be hereinafterdescribed I have provided a flexible guard cooperating with thethreading device having a passage which receives the thread from thetillingcarrier or bobbin to readily admit the thread to the passage, butpreventing it from thereafter flying out, and I have also arranged aguard within and above the deliveryeye of the sh ut-- tle to prevent thethread from getting out of said eye after being once led thereinto.

Figure 1 is a perspective view of a loomshuttle embodying my invention,a fillingcarrier being shown therein. Fig. 2 is a top or plan view ofthe delivery end of the shuttle with the self-threading devices inposition. Fig. 3 is a similar view of the shuttle end with the threadingdevices removed. Fig. 4 is a side elevation of the block forming thethreadingdevices detached. Fig. 5 is an under side view thereof. Fig. 6is an inner end elevation of said block; and Fig. 7 is a longitudinalsectional view of the delivery end of the shuttle with a part of theblockin elevation, taken on the line so 00, Fig. 2.

The shuttle-body A, having the longitudinal opening A therein for thefilling-carrier or bobbin B, has its delivery end cut away or recessedto form a seat (L, Fig. 3, for a portion of the block, to be described,supporting or forming the threading devices, and an open threaddeliveryeye 6 is made in the side of the shuttle-body. (Herein shown as on theleft-hand side.) The threading device is herein shown as supported 011or formed by a block comprising a central and substantially cylindricalbody b, having a threaded shank 1), adapted to enter a counterbored holea in the shuttle-body and secured in place by a suitable nut a. (SeeFig. '7.) Alaterally-extended nearly circular flange or head 12 on thebody I) rests in the seat Ct flush with the upper surface of theshuttle-body, said flange and body being prolonged forwardly to presenta wall bi f or ning one side of a thread,- receiving passage b extendedthroughthe front wall of the body I), (see Figs. 6 and 7,) preferablyenlarged at its lower end, as at If. Back of the slot 11 the body I) ismade open at Z) and rearwardly extended at h to fit into thecorrespondingly-recessed part a of the shuttle-body, forming a widemouth for the thread-receiving passage in front of and adjacent the tipof the filling-carrier B. At the side nearest the delivery-eye e thehead 11 is extended outwardly and downwardly to form a spur b the frontedge of which forms a con tinuation of the outer side of a horn c, thebeak: 0 thereof eirtending into a depression 20 in the wall 12 The hornc has a depending fin 0 extending from a point back of the beak v crearwardly to and inside of the spur b acting with the horn to guide thethread from the receiving-passage Zr to the delivery-eye c. Preferablythe inner part of the horn and the portion of the head 19 at the rearthereof will be inclined, as at 12 toward the entrance of thethread-receiving passage to facilitate entrance of the thread thereto.

Attached to the spur b is a depending lip d, which, when the block is inplace, stands inside of the entrance 6' of the delivery-eye and abovethe latter, said lip forming a guard toprevent removal of the threadfrom the delivery-eye. A notch d in the lower end of the guard holds thethread in case it should accidentally be drawn up toward the entrance 6'of the delivery-eye.

The head b in front of the mouth b of the thread-receiving passageoverhangs the slot b at 11 and is downturned toward the inclined part bof the horn, covering the slot thereat, so that the thread after passingbelow said overhang b will not readily fly out of the slot b before itis guided to the eye.

In order to absolutely prevent the thread from flying out of thethread-receiving passage under any circumstances, I attach a lightflexible guard g to the wall of the slot b under the overhang 'b, thefree end of the guard depending and being held yieldingly against theopposite Wall of the slot. lVhen the thread enters the slot 11 thetension thereon draws it down past the spring-guard g, and the latterwill effectually prevent flying out of the thread thereafter, as theguard extends transversely across and closes the receiving-passage abovethe thread.

The threading operation will be obvious from the foregoing descriptionand the drawings, the thread as it unwinds off of the end of thefilling-carrier B being drawn into the receiving-passage under theoverhang Z)" and then past the guard g. NVhen the thread slips aroundunder the beak c of the horn, it is thereafter guided by the fin c andthe outer side of the horn c to the entrance 6 of the delivery-eye e,and then the thread passes into the eye between the guard (Z and theinner side of the shuttle-Wall.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a self-threading shuttle, a threading device provided with athread-receiving passage, a spring secured to one wall thereof andhaving it's free end depending and extended across the passage at itsrear end, to admit the thread to the passage and thereafter prevent itsremoval, a horn the beak of which crosses the forward part of thepassage, an open delivery-eye, and means to guide the thread theretofrom said passage, substantially as described.

2. In a self-threading shuttle, a threading device provided with athread-receiving passage, an open delivery-eye, a horn to guide thethread thereto from said passage, and a guard on the horn extended downadjacent the inger side oij and above the eye and across its entrance,to prevent removal of the thread from said eye, substantially asdescribed.

3. In a self-threading shuttle, a threading device provided with apassage to receive the thread, a flexible guard to permit entry of thethread thmtoprevent its removal, an. open thread-delivery eye, adownturned guard therefor extended within and above said deliveryeye,and means to guide the thread from. the receiving-passage to thedeliveryeye, substantially as described.

4. In a self-threading shuttle, a metallic block having a longitudinalthread-receivin g passage, a flexible downwardly-inclined guard crossingsaid passage, to prevent removal of the thread, a horn on said block toguide the thread from the passage to the delivery-eye, the shuttlehaving an open thread-delivery eye, and a downturned lip having anotched end, extended within and above the deliveryeye, to preventremoval of the thread therefrom, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

CHARLES E. NUTTING.
